UPS and FedEx, two major cargo airlines, have made the decision to ground their MD-11 cargo planes following a tragic crash at Louisville International Airport in Kentucky. The crash, which occurred on November 4, resulted in the deaths of three pilots and 11 individuals on the ground.

Boeing, the company that acquired the manufacturer of the MD-11 in 1997, advised companies to ground their MD-11s on November 7 for further engineering analysis. This recommendation was made after the Federal Aviation Administration (FAA) issued an emergency airworthiness directive on November 8, effectively grounding all MD-11 cargo planes until a thorough inspection could be completed.

The crash in Kentucky was caused by the detachment of the left engine from the wing of a UPS-operated MD-11 during takeoff. The plane subsequently crashed on the runway and exploded. After conducting investigations, the FAA determined that the issue that caused the engine detachment could potentially occur in other planes of the same design. If left unaddressed, this issue could lead to further safety concerns in the future.

MD-11 cargo planes make up approximately 9% of UPS’s fleet and 4% of FedEx’s. It is estimated that there are currently 70 MD-11s in service among all cargo carriers. In light of the recent crash and FAA directive, both UPS and FedEx have made the responsible decision to ground their MD-11s for the safety of their crew and passengers.

While this may cause some inconvenience and delays in cargo shipments, the top priority for these airlines is the safety of their employees and customers. The grounding of the MD-11 cargo planes is a necessary precaution to ensure the safety and well-being of all those involved in the transportation of goods. Both UPS and FedEx are working closely with Boeing and the FAA to address and resolve any issues with the MD-11s in their fleets.

As investigations continue and necessary changes are made, it is likely that there will be updates and changes to the use of the MD-11 cargo planes. In the meantime, UPS and FedEx are taking all necessary steps to ensure the safety of their operations and the individuals involved.
